Insights into the Biology of Leucocytozoon Species (Haemosporida, Leucocytozoidae): Why Is There Slow Research Progress on Agents of Leucocytozoonosis?

Microorganisms, 2023
Blood parasites of the genus Leucocytozoon (Leucocytozoidae) only inhabit birds and represent a readily distinct evolutionary branch of the haemosporidians (Haemosporida, Apicomplexa).

Exo-erythrocytic development of Leucocytozoon parasites (Haemosporida, Leucocytozoidae) in song thrushes Turdus philomelos

International Journal for Parasitology: Parasites and Wildlife, 2023
Leucocytozoon parasites (Haemosporida, Leucocytozoidae) are haemosporidians whose diversity, exo-erythrocytic development and potential vectors are the least studied. The knowledge about their exo-erythrocytic development and pathogenicity is fragmentary,

Prevalence of Leucocytozoon infection in domestic birds in Ghana.

PLoS ONE, 2023
Leucocytozoon is a haemosporidian parasite known to cause leucocytozoonosis in domestic and wild birds in most parts of the world. It is an important pathogen, as some species can be pathogenic, especially in domestic birds.

Prevalence and Diversity of Blood Parasites (Plasmodium, Leucocytozoon and Trypanosoma) in Backyard Chickens (Gallus gallus domesticus) Raised in Southern Thailand

Animals, 2023
Avian malaria and leucocytozoonosis can cause fatal diseases, whereas avian trypanosomiasis is reported to be harmless in chickens. Backyard chickens can be infected by several pathogens, including blood parasites, that may shed to industrial poultry ...

Disentangling Leucocytozoon parasite diversity in the neotropics: Descriptions of two new species and shortcomings of molecular diagnostics for leucocytozoids

International Journal for Parasitology: Parasites and Wildlife, 2019
Avian communities from South America harbor an extraordinary diversity of Leucocytozoon species (Haemosporida, Leucocytozoidae). Here, of 890 birds sampled, 10 (1.2%) were infected with Leucocytozoon parasites. Among them, two new species were discovered

Blood parasites (Trypanosoma, Leucocytozoon, Haemoproteus) in the Eurasian sparrowhawk (Accipiter nisus): diversity, incidence and persistence of infection at the individual level

Parasites & Vectors, 2023
Background A high prevalence of parasites may result from life-long persistence of infection or from high reinfection rates. We have studied blood parasites in a breeding population of the accipitrid raptor, Eurasian sparrowhawk (Accipiter nisus), to ...

Avian Haemosporidian blood parasite infections at a migration hotspot in Eilat, Israel [PDF]

, 2016
Haemosporidian blood parasites are frequent amongst passerines. Though they often do not cause detectable  consequences to host health, however, their presence or absence and also their prevalence across host  populations may potentially carry ...

Experimental Evidence That Blood Parasite Infection Affects Incubation Patterns in a Cavity-Nesting Songbird. [PDF]

Integr Zool
Chronic blood parasite infections in wild birds can affect their incubation behavior. In pied flycatchers, females with reduced parasite infections incubated for longer than control females. Despite behavioral changes, no immediate effects on fitness were observed.

Continental-scale patterns of pathogen prevalence: a case study on the corncrake [PDF]

, 2014
Pathogen infections can represent a substantial threat to wild populations, especially those already limited in size. To determine how much variation in the pathogens observed among fragmented populations is caused by ecological factors, one needs to ...
